With dual climate control on the driver's side works fine blows cold out of dash vents but on passenger's side blows hot air from dash vents.

Good afternoon,

The actuator is the most common failure.

I attached the procedure for you as well as a picture of the actuator.

You can get the actuator at a parts store.
